I can easily save cron jobs in a file by doing this:

crontab -l > file.txt

And I can restore it with

crontab file.txt

Is there any way to do the same thing with at jobs?

The closest thing that I've managed to find is this:

#!/bin/bash atq for each in $(atq | cut -f 1); do echo "JOB $each"; at -c $each; done

That works but the output is very wordy and there is no way to restore it other than manually going through the output file and re-entering each job.
